ENGAGE 2025 Call For Papers

About

The ACM Siggraph 2001, 2003, 2019 and 2022 saw Geometric Algebra (GA) featured in the form of a Keynote and Courses. The GA community continues to highlight the benefits of employing W. K. Clifford’s GA, quaternions and octonions for computer graphics and vision problems. The advances were presented at the Workshops CGI’2016 on “Geometric Algebra in Computer Science and Engineering” and annually at CGI’2017-2024 on “Empowering Novel Geometric Algebra for Graphics & Engineering (ENGAGE)” and have underlined the power of GA for analysis and computation. GAME2020, 2023, further boost GA and associated algebras as a language for Graphics.

Under the auspices of CGI’25 (July 14-18, 2025), ENGAGE2025 on July 14th in Hongkong, with keynotes by Carlile Lavor (Campinas, Brazil), Hongbo Li (Beijing, China), Francisco Montoya (Almeria, Spain),  will again provide a multi-disciplinary approach from mathematics applied to computer graphics, computer vision and general computer science fields, where GA has strong potential to answer existing mathematical problems.

GA is particularly well suited to allow cross-disciplinary solutions in software engineering as it provides an intuitive and insightful common denominator across mathematical disciplines used in a variety of applications. Understanding GA enables us to relate distinct, seemingly incompatible paths by providing a common geometric and mathematical base.

We invite original contributors in the form of papers, which advance the state-of-the-art in both the application of GA and its instantiation in software and hardware.

Submission Guidelines

Authors should submit papers directly to the CGI LNCS proceedings (CGI 2025 ENGAGE LNCS track), by May 2, 2025. All authors of accepted ENGAGE related papers will be invited either to an oral or poster presentation. For Springer LNCS CGI proceedings author instructions please refer to http://www.cgs-network.org/cgi25/#callforpapers.

Post workshop extended and more advanced ENGAGE papers (with at least 30% new data, algorithms, proofs, figures, etc.) can be published in a topical collection of the SpringerNature journal Adv. in Appl. Cliff. Algs. (AACA), and should have been orally presented at the conference.

AACA author guidelines: https://www.springer.com/journal/6/submission-guidelines. Online submission (deadline: December 31, 2025): https://www.editorialmanager.com/aaca/default2.aspx. At the time of submission, authors must indicate the Topical Collection “TC ENGAGE 2025“.
